9 """Provides the Session class. Sessions are combinations of PtyProcess and
10 Emulation.
12 The stuff in here does not really belong to the terminal emulation framework. It
13 serves it's duty by providing a single reference to TEPTy/Emulation pairs. In
14 fact, it is only there to demonstrate one of the abilities of the framework:
15 multible sessions.
17 Based on the konsole code from Lars Doelle.
